Tilt shift effect is the effect that makes a city, a landscape, anything look like its small. I really like tilt shift photography and you can now make tilt shift photos without the expensive DSLR lenses.

Some cameras record video in interlaced form which is where the i comes from in 720i, 1080i, and 480i. If you want better looking video without the interlaced lines visible, you should de interlace your footage where it looks progressive. Which is where the p comes from in 720p, 1080p, and 480p. Just be sure to do this to your projects before editing, or just do it in your main user settings so it becomes your default sequence settings. This is much easier than dragging and dropping your de-interlace effect to each clip and rendering.
